For an advanced hands-on programmer, do you see a value add in doing Spring 5 certification? There are nuances which can be fine-tuned and knowledge enhanced upon but apart from that, do you have any other insight?
For the ones who plan on giving the certification (out of interest, professional growth or simply to dig deeper) what study approach would you recommend in addition to using your book so as to come out with maximum wealth of knowledge.
I've got certified because the company I worked for at the time insisted upon it. Passing the certification exam is like having a gold medal in the onlympics. You get a medal in your peak moment, but it won't help you much after all. Also,it might look appealing to recruiters. :P
Trully understanding the framework and harnessing its power should be the real goal. My book can help with that because I covered a few XML configuration examples, then gradually migrated to Java configuration and all this is done in a Gradle multi-module project, that contains Spring Boot modules, that use in-memory or containerized databases. The code provided as example can be adapted to real/production situations you might find youself in.
Sure, it can help you considerably with passing the certification, but providing an insight about how Spring really works - that is why I wrote the book.
